Lancaster University, officially The University of Lancaster, is a research-intensive British university in Lancaster, Lancashire, England. The university was established by Royal Charter in 1964 and initially based in St Leonard's Gate until moving to a purpose-built 300 acre campus at Bailrigg in 1968. Lancaster expanded rapidly and now has the 11th highest research quality in the UK and is the 16th highest ranking research institution according to the latest Research Assessment Exercise.

Root system architecture is a fundamentally important trait for resource acquisition in both ecological and agronomic contexts. Because of the plasticity of root development and the almost infinite complexity of the soil, root system architecture is shaped by environmental factors to a much greater degree than shoot architecture. In attempting to understand how roots sense and respond to environmental cues, the striking effects of nitrate and other forms of nitrogen on root growth and branching have received particular attention. This minireview focuses on the latest advances in our understanding of the diverse nitrogen signalling pathways that are now known to act at multiple stages in the process of lateral root development, as well as on primary root growth. © 2014 Elsevier Ltd.

This tutorial outlines the basic theoretical concepts and tools which underpin the fundamentals of phase-coherent electron transport through single molecules. The key quantity of interest is the transmission coefficient T(E), which yields the electrical conductance, current-voltage relations, the thermopower S and the thermoelectric figure of merit ZT of single-molecule devices. Since T(E) is strongly affected by quantum interference (QI), three manifestations of QI in single-molecules are discussed, namely Mach-Zehnder interferometry, Breit-Wigner resonances and Fano resonances. A simple MATLAB code is provided, which allows the novice reader to explore QI in multi-branched structures described by a tight-binding (Hückel) Hamiltonian. More generally, the strengths and limitations of materials-specific transport modelling based on density functional theory are discussed. This journal is © The Royal Society of Chemistry 2015. Source

A method and apparatus for identifying similar and coordinated communications between computers connected by a network are described. Communications between a plurality of pairs of computers are monitored to obtain respective flow metrics for a first and second pair of computers. The flow metric represents at least one property of the data flow between the pair of computers. Representations of the evolution of the data flows between the pairs of computers are updated using the flow metrics. The representations of the evolution of the data flows are compared to determine the similarity of the data flows between the pairs of computers. The first pair of computers and the second pair of computers are identified as exhibiting similar and coordinated communication if their data flows are determined to be similar.

The present invention relates to a method of diagnosing, or providing a prognosis to, or for providing the likelihood of developing, malignant melanoma in a subject, the method comprising the steps of: (a) measuring two or more markers in blood perfusion dynamics at and/or around a skin lesion site; and (b) determining if the two or more markers is different to a normal value. The invention also relates to a device for diagnosing/providing a prognosis to/for malignant melanoma in a subject.

According to some embodiments of the present invention, an avalanche photodiode includes a first electrode, a second electrode spaced apart from the first electrode, a photon absorber layer formed to be in electrical connection with the first electrode, and a charge-carrier multiplication layer formed to be in electrical connection with the second electrode. The photon absorber layer is a semiconducting material that has a first lattice constant, and the charge-carrier multiplication layer is a semiconducting material that has a second lattice constant that is different from the first lattice constant. The photon absorber layer and the charge-carrier multiplication layer are connected together by an interfacial misfit (IMF) array at an interface thereof such that the IMF array provides at least part of an acceleration potential for an avalanche region of the avalanche photodiode.
